Watering twice daily with 1.5L, at a pH of 6.0 and EC 1200-1300.
Nutrients used: Terra Aquatica DualPart for coco*, GrowthTechnology Liquid Silicon(~0.5ml/L), and some seaweed extract(2ml/L).
On day 22, I started with the Pre-Flowering ratio of nutrients.
*I use the ratio between the Grow and Bloom according to label but not the quantity, I use as much as needed to reach the EC level I want.
@Growforsleep, Thanks for you reply!! This is crazy, i've started using Dual part coco and i get cal-mag deficiencies i've never had during veg, if i mix nutes in anything less than 250 ppm cal-mag they develop white spots by the next day ;( i love the product and how the PH holds for 1-2 days but can't seem to get dosages right.
@Matjf420, No, apparently the DualPart has enough calmag to sustain it as per the instructions, but I did buffer the coco with calmag before planting as cocoforcannabis site suggested it.
So in the end I didn't have any deficiency symptoms and everything went great.
